Level 2 generation in SQL access mode
Note: When the logical entity has a default logical server, the instructions related directly to the entity will automatically be assigned to the logical server, except in the SFTKYS_PROCESS sections.
In the example below, <S1> is the default logical server of ENTITY1, and <S2> is the default logical server of ENTITY2.
Only the lines in purple refer to the instructions generated by level 2 generation.

Note:
As regards IE, IP and CA-classes management rules, the $PROP (properties) will be replaced by the file field guide words.
As regards the initialization of variables, the following rules apply:
Blank or zero initialization:
Input/Output fields not used by the data flow and not keys of a view or a load.
